Well, Pac is probably more respected given that he is the quiet, likeable fighter who has turned his career around and become one of the best P4P fighters of our modern era. Mayweather will always be derided because of his brash, arrogant and sometimes vulgar nature. Still, you can't knock his talent or skill. If they ever did fight, Mayweather would beat ac quite handily in my opinion.

Pacquiao hands down. Fighting Barrera/Morales/Marquez all these times alone made him a first ballot hall of famer. I'm not a fan of the factors involved with his fights as he moved up in weight, particularly the catchweights. But hes gone above and beyond.
